What Are Activities of Daily Living (ADLs)?
Activities of Daily Living, or ADLs, are the basic self-care tasks that people need to perform each day to live independently. These are fundamental skills that support an individual's physical health, safety, and well-being. Healthcare professionals, family members, and caregivers use ADLs to measure a person's functional status, identify areas where they may need assistance, and create a care plan.
ADLs are typically divided into two main categories: Basic ADLs (BADLs) and Instrumental ADLs (IADLs). Understanding this distinction is key to comprehending the scope of support a person requires.
Basic vs. Instrumental ADLs
Basic Activities of Daily Living (BADLs): These are the most fundamental and physical self-care tasks. An individual's ability to perform BADLs is a primary indicator of their overall functional independence.
- Examples of Basic ADLs:
- Mobility: Including ambulating (walking), transferring (moving from bed to chair), and bed mobility (moving within the bed).
- Bathing and Personal Hygiene: The ability to wash oneself, groom, and maintain dental hygiene.
- Dressing: The ability to select appropriate clothing and put it on and take it off.
- Toileting and Continence: Managing bowel and bladder functions, getting to and from the toilet, and cleaning oneself.
- Eating: The ability to feed oneself from a plate to the mouth.
Instrumental Activities of Daily Living (IADLs): These are more complex, higher-level skills that support independent living but are not as basic as BADLs. While still important, a person can often delegate IADLs to others more easily than BADLs.
- Examples of Instrumental ADLs:
- Managing Finances: Paying bills and handling money.
- Meal Preparation: Planning and cooking meals.
- Transportation: Driving or arranging rides. Community mobility is an IADL, while functional mobility in the home is a BADL.
- Housekeeping: Performing chores and home maintenance.
- Medication Management: Taking medications correctly and refilling prescriptions.
Why Mobility is a Basic ADL
Mobility is not just an ADL, it is a basic, or fundamental, ADL because it is the foundation for performing many other essential daily tasks. Functional mobility is defined as the ability to move from one place to another while performing ADLs, such as getting in and out of a tub or moving from room to room. Without the ability to move independently, a person's capacity to bathe, dress, or use the toilet is severely impacted.
Aspects of Mobility as an ADL
- Ambulation: This refers to the ability to walk, with or without an assistive device like a cane or walker. It is necessary for moving around the home and maintaining an active lifestyle.
- Transferring: This involves the ability to move from one surface to another. Examples include transferring from a bed to a chair, or a chair to a toilet.
- Bed Mobility: This encompasses smaller movements within the bed, such as rolling over or shifting position. The Centers for Medicare & Medicaid Services includes "getting in and out of bed or a chair" under their definition of ADLs.
Assessing Mobility as an ADL
Assessing a person's mobility is a critical step in determining their care needs and risk for falls. A comprehensive assessment typically involves observation, interviews, and specific objective tests.
- Observation: Healthcare providers, like physical or occupational therapists, observe the individual's movements during routine tasks. They look for signs of unsteadiness, balance issues, or difficulty with transfers.
- Standardized Tools: Tools like the Katz Index of Independence in ADL or the Banner Mobility Assessment Tool (BMAT) are used to systematically evaluate a person's functional level. These tools score independence across a range of activities.
- Timed Tests: Simple, objective tests like the "Timed Up & Go" can quickly assess a person's mobility, walking speed, and balance.
- Assistance Levels: Assessment also involves documenting the level of assistance required, from verbal cues and stand-by assistance to hands-on support or full dependence.
Why It Matters: Implications of Mobility Decline
A decline in mobility has far-reaching consequences for an individual's health and independence. It is often an early warning sign of worsening physical function. Mobility issues can lead to an increased risk of falls, a higher chance of hospitalization, and a lower overall quality of life. Prompt identification of mobility issues through ADL assessments allows for targeted interventions, such as physical therapy, home modifications, and assistive devices, to help maintain independence.
Comparison: Basic ADLs vs. Instrumental ADLs
| Feature | Basic Activities of Daily Living (BADLs) | Instrumental Activities of Daily Living (IADLs) |
|---|---|---|
| Definition | Fundamental tasks for basic self-care and physical survival. | More complex tasks for living independently in the community. |
| Focus | Physical, physiological needs (e.g., body movement, hygiene). | Cognitive, organizational, and social skills. |
| Examples | Ambulation, bathing, eating, dressing, toileting. | Managing finances, preparing meals, transportation, housekeeping. |
| Delegation | Cannot be easily delegated; intimate personal tasks. | Can be delegated or outsourced (e.g., hiring a housekeeper, paying for transportation). |
| Decline Progression | Typically affected later in the course of aging or disease. | Often affected earlier in conditions like dementia. |
| Independence Level | Loss of these skills indicates significant dependence on others. | Loss of these skills can reduce independence but does not always require hands-on personal care. |
How to Support Mobility as We Age
Promoting safe and independent mobility is a cornerstone of effective senior care. Here are some strategies:
- Home Modifications: Making the home environment safer can significantly reduce fall risk. This includes installing grab bars in bathrooms, adding handrails on stairs, and ensuring adequate lighting.
- Physical and Occupational Therapy: Therapists can work with older adults to improve strength, balance, and coordination. They also provide training on how to use assistive devices properly.
- Regular Exercise: Activities that maintain muscle strength, flexibility, and balance are vital. Examples include walking, Tai Chi, and strength training.
- Assistive Devices: Canes, walkers, and wheelchairs can be invaluable tools for maintaining safe mobility.
- Caregiver Assistance: Having a caregiver available for stand-by assistance or hands-on help can provide confidence and safety during transfers and ambulation.

Conclusion
In summary, mobility is undeniably a basic Activity of Daily Living, and it's a fundamental measure of an individual's independence and functional health. For senior care, the assessment and support of mobility are crucial for maintaining safety, dignity, and quality of life. By understanding the components of mobility as an ADL and differentiating it from more complex instrumental tasks, caregivers and families can provide more effective, personalized care that promotes independence and well-being for as long as possible.
